How Daddy met Mommy

“Daddy, how did you first meet Mommy?” I asked.
Daddy chuckled and held up a quarter. “With this.”
I scratched my head, confused.
“Jim bet heads. I bet tails. It’s as simple as that really. I won the bet to date Mama,” he explained.
“Really?”
“Yep,” Dad answered. “Uh... don’t tell your mama that, though.”
